In the display panel 110 and the display device provided in the embodiments of the present invention, the electromagnetic device is disposed between the middle frame 10 and the back plate 20, and repulsive magnetic force is generated between the middle frame 10 and the back plate 20, so that a gap is generated between the back plate 20 and the middle frame 10 for buffering and damping. In addition, the electromagnetic device can also control the strength of the magnetism in a subarea manner, so that the magnetism of the bending area 112 is larger than that of the non-bending area 111, the stress generated by bending of a part of the display panel 110 is resisted, the display panel 110 is further protected, and the time service life of the display panel is prolonged.
